This alloy is suitable for production of highly stressed components of large cross section for aircraft, automotive and general engineering applications, such as forged propeller shafts, connecting rods, gear shafts, crankshafts and landing gear components.

This page cover the AISI 9840/AISI9840 Chemical element, Mechanical Properties, AISI9840 Datasheet, Cross Reference of AISI9840 Mainly used for Former SAE Standard and Former SAE Ex-Steels.

AISI 9840 is defined as Cr-Ni-Mo series alloy steel as per USA standard ASTM A519.AISI 9840 steel is very similar to AISI 4340 steel, only the Ni element is lower, and the difference in other elements is almost negligible.

AISI 9840 is a nickel-chromium-molybdenum steel very similar to AISI 4340 with lower nickel and slightly higher manganese. In the heat treated condition it has good combination of strength, fatigue resistance, toughness and wear resistance.
